Transformations: Dilation
Dilation: A ________________________________________ in which a figure is made __________________
or _____________________ with respect to a ___________________ called the ___________________ of
____________________________.
Label it. Example: The ____________ polygon has
been Dilated (made ____________________)
to form the ___________ polygon.
Vocab! Guided Notes
Center of Dilation: The __________________ from which a figure is _______________________.
When ______________________ on the Cartesian Plane, the __________________ is of the
___________________ of Dilation.
Example: Here, the ______________________ ( , ) is the
____________________ of Dilation. Label the Center of Dilation.
Scale Factor: In a dilation, the __________________________ figure and dilated _________________
are ___________________. The ratio that compares the one with the other is called the
__________________ __________________ and is called _____.
Example: The ____________ square is twice the
size of the _________ square. (label them according
to the PowerPoint!)
If _________ à ____________,
the what is the scale factor? k =________
What if ____________ à _________? k =________
Dilation on the Cartesian Plan: To __________________ a figure in respect to the origin,
_______________________ the coordinates of each _________________ by the scale factor, _____.
Transformation Notation of Dilations: (x, y) à ( , )
Classifying a Dilation by the Scale Factor:
When _____ > ______, the dilation is a _____________________________.
When _____< _____ < _____, the dilation is a ___________________________.
Example 1!
Dilate ΔABC by the scale factor, k = ______, then classify it.
This Dilation is a(n)
__________________________.
Because _________________
___________________________.
Dilate ΔABC by a scale factor, k = ______ then classify it. 1)
A: _____________ A’: _____________
B: _____________ B’: _____________
C: _____________ C’: _____________
Example 2!
Dilate Rectangle
WXYZ by the scale
factor, k = ________
(or __________), then
classify it.
This dilation is a _________________________ because
the scale factor is ____________________________________
__________________________________________________________.
You try it!
This Dilation is a(n) _____________________________.
2)
3)
Dilate ΔXYZ by a scale factor, k = ______, then classify it.
Dilate ΔJKL by a scale factor, k = ______. Then translate it down
______ and to the right ______ units.
X: _____________ X’: _____________
Y: _____________ Y’: _____________
Z: _____________ Z’: _____________
This Dilation is a(n) _____________________________.
J; ____________ K:____________ L:____________
J’: ______________ J”: ______________
K’: _____________ K”: _____________
L’: _____________ L”: ______________
This Transformation is both
a(n) _____________________________
and a _____________________________.
